Equipment for controlling a train fire in a long railway tunnel and method for implementing same

Abstract

The invention relates to equipment including fixed fire detectors (10) along the track (100) and fixed extinguishing stations (20) installed in the tunnel. Each station is provided with fire detectors (23) for locating the source, an automatic configuration system for targeting the area to be sprayed, individually controlled spraying devices (22), and a device for remotely or locally activating the spray. The station is preceded by a train stopping area (ZA) in which the train (TRO) starts a stopping sequence and slows down from the safety speed thereof to the zero speed thereof. A control center (30) manages the operation of the equipment and in particular orders a reduction of the train (TRO) running speed when the detectors (10) have detected a fire (flames, smoke, CO). The reduced speed (safety speed (Vs)) enables the train (TRO) to run as quickly as possible while mitigating the progression of the fire.

Description

FIELD OF THE INVENTION[0001]The present invention relates to equipment for controlling a train fire in a long railway tunnel, in particular a train such as a shuttle transporting vehicles and in particular heavy goods vehicles.PRIOR ART[0002]There are various methods of controlling a train fire in a long railway tunnel. These methods generally entail managing the running of trains upstream and downstream of the train which is on fire and gaining access to the train which is on fire either via the railway tunnel or also via the service tunnel. These methods of controlling a tire are, however, traditional methods whose main drawback is that they take a very long time to implement, for instance an hour or so in a very long tunnel, which enables the fire to reach its full height and cause major damage not just to the train but also to the tunnel infrastructure.[0003]This damage is especially serious as its repair is a long and tricky operation because of access conditions to the repair ...

AI Technical Summary

Benefits of technology

This system enables rapid fire control within minutes, limiting damage by confining the fire with localized high-pressure water mist and managing airflow to reduce smoke propagation, effectively targeting the fire source while conserving water resources.

Problems solved by technology

These methods of controlling a tire are, however, traditional methods whose main drawback is that they take a very long time to implement, for instance an hour or so in a very long tunnel, which enables the fire to reach its full height and cause major damage not just to the train but also to the tunnel infrastructure.

This damage is especially serious as its repair is a long and tricky operation because of access conditions to the repair site and because of the consequences of a partial or complete shutdown of the tunnel.

These fire problems occur in particular in long railway tunnels, i.e. whose length does not make it possible for a train on which a fire has started to continue to run in the hope of reaching the tunnel exit so that the fire can then be extinguished.
